Java Integer intValue() Method

The intValue() method is an instance method of Integer class under java.lang package. This method returns the value of the specified number as an int. It is inherited from the Number Class.

Syntax:

Following is the declaration of intValue() method:

Parameter:

DataType	Parameter	Description
NA	NA	This method does not accepts any parameter.

Returns:

The intValue() method returns the numeric value represented by this object after conversion to type int.

Exceptions:

Compatibility Version:

Java 1.2 and above

Example 1

public class IntegerIntValuetExample1 {
	public static void main(String[] args) {				
	      Integer object = new Integer(25);	 
	      // returns the value of this Integer as an int
	      int i = object.intValue();
	      System.out.println("Value of i is: " + i);
        }
}

Output:

Value of i is: 25

Example 2

public class IntegerIntValuetExample2 {
	public static void main(String[] args) {				
	  // get number as float
        Float x = new Float(568f);
        // print the value as int
        System.out.println("Integer Value of X: "+x.intValue());
        // get number as double
        Double y = new Double(55.76);
        // print the value as int
        System.out.println("Integer Value of Y: "+y.intValue());
        }
}

Output:

Integer Value of X: 568
Integer Value of Y: 55

Example 3

import java.util.Scanner;
public class IntegerIntValuetExample3 {
	public static void main(String[] args) {				
		// input number from console
		System.out.print("Enter The Desired Integer Value: ");
		Scanner readInput = new Scanner(System.in);
		int i = readInput.nextInt();
		readInput.close();
		Integer myValue = new Integer(i);
		System.out.println("Integer Value is: " + myValue.intValue());
        }
}

Output:

Enter The Desired Integer Value: 2342
Integer Value is: 2342

Example 4

public class IntegerIntValuetExample4 {
	public static void main(String[] args) {	
	    int x = 66;
	    int y = 5;
	    Integer i = new Integer(x);
	    int result = i.intValue()/y;
	    System.out.println("Value is = "+result);		
        }
}

Output:
